We are told that everyone knows it's all over but they are afraid to tell the person who lost the election and so they are humoring him and indulging his fantasies until they can no longer do so...in about a week or so.
Indulging an old man? Senility surely is the cause of that indulgence. Being kind to an insane man who has only his world of delusion to live in because reality is something he cannot accept.
So they indulge and play along and pretend and lie. My oh my.
